Abstract: 607,876. Regulating. THOMPSON PRODUCTS, Inc. Aug. 23, 1945, No. 21563. Convention date, July 17, 1944. [Classes 7 (iii) and 7 (vi)] Anti-knock fuel (e.g. a mixture of water and alcohol) is injected into the main air-stream either with the ordinary fuel, or separated therefrom, above a predetermined supercharging pressure, the supply of ordinary fuel being decreased when the anti-knock fuel is being injected. The anti-knock fuel, supplied at constant pressure by the pump P with an adjustable byepass, is controlled by a cut-off valve 19 and metering valve 20 attached to a stem 18 connected to a bellows 21 subject to the pressure of the fuel on the inside and supercharging pressure on the outside and actuated by a crank-lever 16 controlled by a capsule 12 exposed to the supercharging pressure through a pipe 10. The valve 19 opens at a predetermined supercharging pressure, the anti-knock fuel being injected through a nozzle 29 with the main fuel flowing from a metering device 35, having an idling jet 32, cruising jet 34, and an economiser jet 39 which only operates at high power outputs, e.g. take-off. Opening of the valve 19 causes an arm 47 on the spindle of lever 16 to close an electrical circuit exciting the solenoid 42 to actuate a needle 40 to reduce the flow through the jet 39, collars 45, 46 limiting the travel of the needle. A capsule 52, normally expanded by the pressure of the anti-knock fuel to keep the contacts 56 closed, collapses if the supply fails, -thereby breaking the circuit and .preventing operation of the needle 40. Hand controls 59, 60 are provided for the valves 19 and 40 to modify the automatic operation when desired.

Filed: 1951-09-24
Abstract: 696,733. Converting. WELDING RESEARCH Inc. Sept. 24, 1951 [Dec. ]2, 1950], No. 22293/51. Class 38 (ii). In a converting circuit for supplying a welding load 51 from a welding transformer W having three primary windings W31, W38, W45 connected to a three-phase supply L, L2, L3 through pairs of back-to-back connected discharge valves 34, 35, 41, 42, 48, 49, as described in Specification 654,583, each winding has connected in parallel with it one of three windings T31, T38, T45 of a separate transformer T. Thus when one winding, e.g. W31, of the transformer W is energized, its parallel winding T31 is also energized, and through its inductive coupling with the other two windings T38, T45 windings W38, W45 are energized. Thus all three primary windings of the welding transformer carry current continuously instead of for one-third of the time. By this means the operating characteristics and the capacity of the welding transformer, and the commutation of the valves are improved. The windings W31, W38, W45 may be in two series-connected halves separated by the valves.

Abstract: 359,560. Water-supply for baths, wash-basins, and cisterns. GUNDRY, A. R., East Indian Railway, Jamalbur, India. July 25, 1930, No. 22494. [Class 26.] A water service installation for railway vehicles &c. comprises a reservoir with pipes leading to supply points, a pump, preferably centrifugal, for forcing water through the pipes, a normally idle motor for driving the pump, and combined drawoff and motor control devices at the supply points whereby the motor is set in operation whenever water is to be drawn off. A tank 1, Fig. 3, to which a reserve tank may be connected, has a sump 4 into which opens the suction pipe of a centrifugal pump 6 delivering through a non-return valve 11 and pipes 10, 12, 14, &c. to service points with taps &c. combined with switches controlling an electric motor which drives the pump when the taps &c. are opened. A pressbutton tap 20, Fig. 4, supplying a wash-basin, has a rod 21 connected to the pressbutton 23 and to a lever 28, pivoted at 24<1>; a contact blade 26, co-operating with contacts 30, is knee-jointed to the lever 28 and is acted on by a U-spring 29 to give a quick break when the switch is opened, which may precede complete closure of the tap. In a flushing cistern, Fig. 6, which is emptied by opening a cock 54, Fig. 3, a float arm 34 is connected by a link 35 to a lever 36 pivoted at 37 and having a cam 43 against which a spring 48 presses a bowl 46 slidably supported in a bifurcated switch arm 44 also pivoted at 37 and co-operating with contacts 52 ; stops 44<1>, 44<2> limit movement of the switch arm. In operation, when the float rises or falls, the arm 36 is moved until the bowl 46 rides over the crest of the cam 43, the spring 48 then rocking the switch arm to break or make contact with a snap action. To prevent loss of water through leakage, refilling of the flushing tank is prevented while the lavatory door is unlocked by the provision of a secondary switch, Fig. 8, comprising a pivoted cam member 58 pressed by a spring 60, the cam being rocked when the door bolt 55 is shot, whereby a switch arm 61 is forced between contacts 62. In a shower bath, Fig. 10, a platform 63 is tilted by the bather and acts through a rod 63<1> to operate a cock 63<2> and switch 64 ; a spring or counterweight returns the platform.

Title: Improved engine for operating vehicle or other doors by compressed air
IPC: E05F15/56
Filed: 1932-08-11
Abstract: 400,745. Pneumatic door-operating appliances. PETERS & CO., Ltd., G. D., CARDWELL, C. H., and ARTHURTON, R. I. D., Windsor Works, Slough, Bucking- hamshire. Aug. 11, 1932, No. 22548. [Class 65 (i).] A fluid-pressure engine for closing vehicle doors which are opened by band has means whereby, after a predetermined portion of the power stroke of the piston effected by fluid pressure acting on the side thereof remote from the piston rod, motive fluid will be admitted to the cylinder to act on the piston-rod side of the piston so that during an intermediate portion of said power stroke the engine operates as a differential piston engine with the movement of the piston retarded by the counterpressure so set up on the piston-rod side of the piston, this admission of motive fluid being shut off before the piston reaches the end of its stroke and the motive fluid thereafter trapped between the piston-rod side of the piston and the cylinder head acting to cushion the piston effectively during the final portion of the power stroke. By this means, should the movement of the piston be stopped during its stroke after a predetermined travel, due to an obstruction in the path of the door, sudden and rapid movement of the piston and slamming of the door on removal of the obstruction will be prevented by pressure fluid from the source of supply acting on the opposite face of the piston. The full power is effective for quickly starting the stroke, and the speed of movement is not greatly reduced while the engine acts differentially as less power is needed to maintain the motion of the door than to start it. A pneumatic engine is shown, comprising a cylinder 1, with end caps 2, 3 constituting fixing brackets for the engine, and a piston 8 with a relatively large piston rod 10 which is connected at 12 by any means to the door or mechanism to be operated. Fluid pressure is supplied to the cylinder through a passage 6 in the end cap 3, and the end cap 2 is provided with a small exhaust port 13, the section of which is adjustable by a needle valve 14 with a locking nut. At appropriate distances from the ends of the cylinder ports 16, 17 extend through the cylinder wall into a space 19 formed between the cylinder wall and a dished cover brazed or welded to the outside of the cylinder. The passage 19 and ports 16, 17 are made larger than the exhaust port 13, so that when the piston is between the ports 16, 17 pressure fluid will flow through the passage 19 into the space on the left of the piston faster than it can escape through the port 13. When the piston passes to the left of the port 17, this flow of fluid is cut off, and the motion of the piston is cushioned by the fluid trapped in the left-hand end of the cylinder, owing to the restricted exhaust port 13. The passage 19 may be formed by a pipe connected at its ends to the ports 16, 17, or by a helical groove or recess cut in the inside of the cylinder wall.
